Short answer
An MT103 is the Swift message type "MT 103 Single Customer Credit Transfer".1 Banks used it to send a customer's cross-border payment instruction.1 The coexistence period for moving cross-border bank-to-bank payment instructions to ISO 20022 ended on 22 November 2025.2 MT 103s still sent are converted, for a charge, to their ISO 20022 equivalent.2

Clients and banks still talk about "sending the MT103" as proof that a payment has left. If you are a consultant waiting on a US client, or an agency reconciling receipts from Europe, this page explains what an MT103 is and why, since 22 November 2025, the name refers to an older format.2
What does MT103 mean in simple words?
An MT103 is the bank message that carried a foreign client's payment to your bank, and a copy of it was the usual proof that a wire was sent.15 Swift's Category 1 standards list the message as "MT 103 Single Customer Credit Transfer", with variants MT 103 STP and MT 103 REMIT.1
- Tracking reference: Every MT 103 must carry a 36-character Unique End-to-end Transaction Reference (UETR) in field 121, created by the paying bank and passed unchanged along the chain.5
- Status: Since 22 November 2025, MT payment instructions are no longer supported on Swift's FIN service for cross-border bank-to-bank flows.2
In everyday use, "MT103" still means "the bank's record that the payment left".15
Why does the MT103 matter for Indian exporters and freelancers?
The MT103 matters because it is the document clients reach for when a payment is late, and the format change affects what that document looks like.25
- Proof of payment: A client's bank may send an ISO 20022-based confirmation rather than a classic MT103 printout. What matters is the UETR, which every bank in the chain can use to find the payment.5
- Reconciliation: Swift says ISO 20022 carries more remittance information, which can make it easier to match a receipt to an invoice.3
- Missing detail: Swift notes that converted messages lack structured, rich data, so a payment from a bank still sending MT 103s may arrive with less detail.2
For most exporters, the change is invisible: your client still pays by international wire, and your bank still credits you after its usual checks.2
How did the move from MT103 to ISO 20022 work?
ISO 20022 replaced the MT format for cross-border payment instructions between banks, after a coexistence period.2 Swift describes ISO 20022 as "an open global standard for financial information" that carries consistent, rich and structured data.3 The key dates, according to Swift, are:2
| Date | What happened |
|---|---|
| 22 November 2025 | Coexistence of MT and ISO 20022 for cross-border bank-to-bank payment instructions ended |
| From 22 November 2025 | MT 103s still sent are checked and converted to ISO 20022 under contingency processing |
| 1 January 2026 | Charges for contingency conversion started |
| 1 January 2027 | Contingency charges are due to increase |
Swift says contingency processing is a short-term measure.2
How do you use an MT103 or its replacement to trace a payment?
You use the payment confirmation, whatever its format, by taking the UETR from it and giving it to your bank.5
- Ask the client: Request the payment confirmation from the client's bank, in the format it now issues.2
- Find the UETR: Look for the 36-character reference that was carried in field 121.5
- Give it to your bank: Share the UETR and the invoice number so the bank can identify the payment.5
If your bank cannot identify a payment from a tutor's student or a marketing client, the UETR and the invoice number are the two details to give it.
What is the difference between an MT103 and a pacs.008 message?
An MT103 is the older Swift MT message for a customer credit transfer, and pacs.008 is the ISO 20022 message Swift now names alongside it.14 Swift's gpi pages refer to customer payments as "MT103/pacs.008", meaning the old and new message for the same kind of payment.4
| Message | Standard | Status for cross-border bank-to-bank payments | Best for |
|---|---|---|---|
| MT 103 | Swift MT | No longer supported on FIN since 22 November 2025; converted under contingency processing2 | Reading older payment records and proofs |
| pacs.008 | ISO 20022 | The format used in its place, with richer structured data34 | Current cross-border customer payments |
Ask for whichever confirmation your client's bank produces; both identify the payment by its UETR.5
What do people get wrong about the MT103?
The common mistake is insisting on a classic MT103 printout that the client's bank may no longer produce.2
- Format: A missing MT103 does not mean a payment was not sent; the confirmation may now be ISO 20022-based.2
- Data: Converted messages do not contain structured and rich data, and may be aborted if they cannot be translated.2
The UETR is the reliable detail in any proof of payment.5
Which terms are related to MT103?
These terms come up alongside the Swift payment message:
- Swift gpi and UETR: the tracking service and reference that follow the payment.
- SWIFT code: the code that identifies each bank in the message.
- Wire transfer: the payment the message instructs.
- Correspondent bank: a bank in the chain that passes the message on.
- Inward remittance: the payment as your Indian bank records it.

Frequently asked questions
Can an Indian bank still send an exporter an MT103 copy?+
Possibly not as a true MT103. Swift says MT payment instructions are no longer supported on FIN for cross-border bank-to-bank flows since 22 November 2025.2 An Indian exporter should ask for the payment confirmation in whatever format the bank now issues, and make sure it shows the UETR for the payment.
Why do clients send an MT103 as proof of payment?+
Clients send an MT103 because it carries the payment's details and its 36-character UETR in field 121, which any bank in the chain can use to locate the payment.5 For an Indian exporter, the UETR on that document is the part that helps the Indian bank trace and match the incoming wire.
Do converted MT103 messages lose information?+
Swift says converted MT messages do not contain structured and rich data, and may be aborted if they cannot be translated.2 A payment from a client's bank that still sends MT 103s may therefore reach an Indian exporter's bank with less remittance detail, so share the invoice number with the bank.
When did Swift start charging for converting MT103 messages?+
Swift says charges for contingency conversion of MT payment instructions to ISO 20022 started on 1 January 2026, and are due to increase on 1 January 2027.2 These charges fall on the banks that still send MT 103s, and how a bank passes them on depends on its own pricing.
Is the contingency conversion of MT103 messages permanent?+
No. Swift says contingency processing, which checks and converts MT 103s still sent after 22 November 2025, is a short-term measure and not an alternative to adopting ISO 20022.2 Banks are expected to send cross-border customer payments in the ISO 20022 format instead of relying on conversion.
